Add method toString to Location entity:
将方法toString添加到Location实体：
public function __toString()
{
return $this->getNaam();
}
then clear cache:
然后清除缓存：
bin/console cache:clear
The problem is that you are including Location entity to Stock form and symfony need to render somehow every location, so you need choose how it will be shown in form, toString could return any property that you want.
问题是你将Location实体包含在Stock表单中，而symfony需要以某种方式呈现每个位置，所以你需要选择它将如何在表单中显示，toString可以返回你想要的任何属性。
